Yes.

Of course you can. Branded products are more conducive to selling.

Before putting any product on the shelves, you need to check the market to see if anyone has sold it and whether there is a certain market demand. If AliExpress does not have a category for your product, you don’t need to consider it. Similarly, if a product is rarely sold in the market and no one is interested in it even if you open a through train, it is better to give up decisively.
